never tried pam, we have however tried waxing the blades with ski wax. worked well for about 1-2 hrs then wore off. but, there is a product called "SLIDE" used on highway snow-plows that keeps the snow from sticking.It's a liquid that can be sprayed, brushed,or rolled on ,then must dry. breaks the surface tension kind of like rain-x. it works well but must be reapplied every couple days. a stainless steel or "plastic blade skin" maybe a more permanent solution if its a common issue. ask your local groomer dealer about them
